The Research For The Operation Characteristics And The Processing Performance Of Anaerobic Baffled Reactor (ABR) Treating Soybean Wastewater

Anaerobic Baffled Reactor (ABR) is a class derived from multi-phase anaerobic reactor stages (Staged Multi-Phase Anaerobic Reactor, SMPA) theory of the third generation of a new anaerobic reactor. It is an environmental research by the advent of workers has become a research hotspot. Papers for the Study of Anaerobic Baffled Reactor (ABR) wastewater treatment performance of soy protein and its operation characteristics, ABR reaction chamber of 4 grid control strategy operation of the system was studied, using the effective volume of 42 L of the four-frame room ABR, MLVSS in the sludge inoculum was 18.0 g·L-1, influent COD concentration of 2000mg·L-1,HRT 48 h, (35±1℃and other conditions (ie OLR1.0 kg·(m3·d)-1), running through a period of 80 d to study the influent COD concentration was increased based on the organic load (OLR) to change the impact of its processing power, can be successfully started within 31 d and reached a preliminary stable operation of the ABR, COD removal rate of 96%; ABR OLR has a strong anti-impact ability, when the OLR by a 1.0kg·(m3·d)-1 gradually increased to 6.0 kg·(m3·d)-1 when, ABR can still achieve safe and stable operation, during operation, determine the impact of water quality indicators in respect of each parameter of different organic loading, ABR reactor COD removal efficiency and gas production. By measuring the ABR in the cultivation of anaerobic sludge characteristics, and explore the low concentration of wastewater treatment sludge acclimation law ABR, ABR granulation and reduce the possibility of a reactor startup period. Of organic materials in anaerobic baffled reactor degradation of frame by frame, Of volume loading (VLR), hydraulic retention time (HRT), pH, oxidation reduction potential (ORP), alkalinity (ALK) and the VFA, and several other parameters on the performance of ABR operation of the system, stability and the impact of gas production and quantify these factors and the regulation of the optimum operating parameters. And this system is running Succession of microbial community change and analyzed. Based on the research and development in the ABR response and efficient equipment, and successfully applied to biological hydrogen production by fermentation of soybean protein production technology and waste water treatment under study provided.
